Bug 318715 – sys-auth/consolekit-0.4.1 crashes if /etc/ConsoleKit/seats.d under svn

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Mark Purtill 2010-05-06 03:20:36 UTC]

If the directory /etc/ConsoleKit/seats.d/.svn exists, consolekit crashes.

This is fairly serious because if kde is compiled with the consolekit flag, it prevents logging-in via kdm.

Reproducible: Always

Steps to Reproduce:
Put /etc/ConsoleKit/seats.d under svn and do

/etc/init.d/consolekit restart

Actual Results:  
I find the following in /var/log/messages:

May  5 20:13:21 buurin kernel: console-kit-dae[8331]: segfault at 18 ip 000000000040cb29 sp 00007fff01a88230 error 4 in console-kit-daemon[400000+1d000]

and console-kit-daemon does not appear to be running.

Expected Results:  
No crash

Moving the .svn file out of the way appears to prevent the crash; at least, the error message doesn't show up in /var/log/messages and console-kit-daemon appears to be running.

This started happening after upgrading from consolekit-0.3.0-r2 to consolekit-0.4.1.  See also <http://forums.gentoo.org/viewtopic-t-818649-start-0.html>.

I have the same issue with the identical segfault, but i change "hidden=true" in /etc/ConsoleKit/seats.d/00-primary.seat to hide consolekit threads in htop output.
I think perhaps it is the same bug:

http://cgit.freedesktop.org/ConsoleKit/commit/?id=f01e054a419d7aaf10c1da321bfbff554ffc3c54

I hope this can help.
